NHTSA Complaint #11694978 — 2017 FORD F-150

Complaint Summary (What Happened): The cam phasers (variable camshaft timing system) failed on my 2017 Ford F-150 4x4 with the 3.5L EcoBoost engine. This is a widely known issue on these engines. The failure causes a loud rattling/knocking sound during startup and can lead to engine timing problems or internal damage. My truck only has 108,000 miles, has been well maintained, and is just outside of the extended warranty coverage Ford issued for this exact issue. Safety Risk: The cam phaser failure causes erratic engine timing, which can lead to power loss or stalling during operation. This creates a safety hazard while merging, towing, or driving at highway speeds. The loud knocking sound and hesitation also distract the driver and reduce confidence in the vehicle’s reliability and acceleration when needed for safety. Problem Confirmation: Yes, the problem was confirmed by a Ford dealership. They diagnosed cam phaser failure and quoted approximately $6,300 for the repair. Inspection: The vehicle has been inspected by a Ford dealership service department. Ford Motor Company was contacted but declined to assist financially since the issue occurred just after the extended warranty expired. Warning Signs: No warning lights or messages appeared before the failure. The first symptom was a loud rattling/knocking noise on cold start, which worsened over time. The issue started around 85,000 miles. The check engine light just came on at 108,000 miles. Availability for Inspection: The failed components remain installed on the vehicle and are available for inspection upon request. However, I am looking to get this fixed as soon as possible.
